Error in using Launchpad get_fw_by_id

Hi,

I’m trying to use firework in python to read through my mongodb. However, when I invoke launchpad.get_fw_by_id, I get the following error. Its got to do with compatibility with pymatgen (which renamed io.vaspio module to io.vasp). However I could not identify which file this is getting set and it will be of great help
if you can help me address it. I’m using the latest stable versions of fireworks, pymatgen and monty as available in pip.

It looks like you have a serialized object in your firework spec that can no longer be reconstructed via recursive_load, since the code from which it was constructed (in this case, pymatgen) has changed. You can either update the spec of the existing fireworks such that deprecated objects are replaced with current ones, or you can revert to a prior version of the code used to generate that object such that the module that was changed (in this case pymatgen.io.vaspio) is concurrent with the serialized object.

Best,

Joey

There is another (probably preferred option) of using the FW_NAME_UPDATES key in the FWConfig to update the _fw_name of the refactored files. The format of that is a dictionary; each key is the old _fw_name, and the corresponding value should be the new _fw_name

I have not done this before and I have not made any changes myself. I have only installed the packages from pip. Can you tell me the pymatgen version that was used to serialize the latest version available in pip and I can install that version of pymatgen in my system.

Gosh. I now understand. I was using a deprecated fireworks_vasp module to create the database and which in turn used the vaspio module of pymatgen which has since been deprecated. The problem was that information was missing from the error message. I created the vaspio module manually inside pymatgen.io and it now works. Although I still dont understand anubhavs answer. Say if I create a new updated package say fireworks_vasp2 that provides that is compatible with pymatgen. How do I provide this information in FW_Config. I have three firetasks bundled in each firework and they have different classes as _fw_name

firewoks_vasp.tasks.WriteVaspInputTask, firewoks_vasp.tasks.VaspCustodianTask and firewoks_vasp.tasks.VaspAnalyzeTask.

``

How do I use the FW_NAME_UPDATES so that it can systematically change the names of the three firetasks?

It looks like you have a serialized object in your firework spec that can no longer be reconstructed via recursive_load, since the code from which it was constructed (in this case, pymatgen) has changed. You can either update the spec of the existing fireworks such that deprecated objects are replaced with current ones, or you can revert to a prior version of the code used to generate that object such that the module that was changed (in this case pymatgen.io.vaspio) is concurrent with the serialized object.

To set up the config file:

Add something like

FW_NAME_UPDATES: {<old_name>: <new_name>}

I’m trying to use firework in python to read through my mongodb. However, when I invoke launchpad.get_fw_by_id, I get the following error. Its got to do with compatibility with pymatgen (which renamed io.vaspio module to io.vasp). However I could not identify which file this is getting set and it will be of great help
if you can help me address it. I’m using the latest stable versions of fireworks, pymatgen and monty as available in pip.
